Does anyone know if this is on Chromium's bug tracker, or if it's a deprecation (planned or unplanned) or bug? |

Having the same issue. const readAsArrayBuffer = (blob: Blob) => {
return new Promise(resolve => {
const reader = new FileReader()
reader.readAsArrayBuffer(blob)
reader.onloadend = () => {
resolve(reader.result)
}
})
}
const injectMetaData = async (blob: Blob) => {
try {
const decoder = new Decoder()
const reader = new Reader()
reader.logging = false
reader.drop_default_duration = false
const buffer = (await readAsArrayBuffer(blob)) as ArrayBuffer
const elms = decoder.decode(buffer)
console.log("elms", elms)
elms.forEach(elm => {
reader.read(elm)
})
reader.stop()
const refinedMetadataBuf = tools.makeMetadataSeekable(reader.metadatas, reader.duration, reader.cues)
const body = buffer.slice(reader.metadataSize)
return new Blob([refinedMetadataBuf, body], { type: blob.type })
} catch (error) {
console.error(error)
}
}I got this from the log Number 36 which has type and name is I don't know what is the correct way to solve this. I am filter the unknown and invalid type one out to bypass this issue for now. ...
let elms = decoder.decode(buffer)
const validEmlType = ["m", "u", "i", "f", "s", "8", "b", "d"] // This is from elm type of the lib
elms = elms?.filter(elm => validEmlType.includes(elm.type))
elms.forEach(elm => {
reader.read(elm)
})
reader.stop()
.... |

After further investigation, I suppose chrome change how is webm generated and start using Matroska Element 0x55b*. These elements are neither in schema.js in dependency package "matroska" nor in "node-ebml". I don't why there were ignored. I post an issue here oeuillot/node-matroska#8 In my case I use ts-ebml for the duration so, for now, I will do like @tonynguyenit18 |

Any progress here? are we just going to remove the data with unknown type? |
|
I've just created oeuillot/node-matroska#9 to update |

+1 |
Matroska v2.2.4 breaks ts-ebml and now gives wrong duration |

Hi,
Since I installed the last version of chrome on my mac (macos 11.4) decoding and reading file generate with MediaRecorder throw an exception: "No schema entry found for unknown"
An EBMLElement has unknown in schema.
I have made an exemple here. just start and stop recording.

Perhaps it is a bug in Chrome but so far I don't find it in tracker.
Thanks
